Answer:
None of these answers are correct.
Step-by-step explanation:
Perpendicular lines have opposite and reciprocal slopes, which means that we take the slope and we flip it. After we've done that, we change the sign.
Since the original slope is -7, first we flip it and get -1/7. Now we change the sign and get 1/7. Therefore, the perpendicular slope of this line would be 1/7

Answer:
yes. -40°C = -40°F
Step-by-step explanation:
The relationship between the two temperature scales is ...
C = 5/9(F -32)
If we set the numerical values equal, we have ...
F = C
F = 5/9(F -32) . . . . .substitute for C
9F = 5(F -32) . . . . . multiply by 9
4F = -160 . . . . . . . . eliminate parentheses, subtract 5F
F = -40
The two temperature scales have the same value at -40°.

That's the bottom mark on the thermometer scales attached. (Unfortunately, those scales seem to be slightly misaligned. 0°C doesn't line up exactly with 32°F, either. Oops.)
